Roadhog is currently not in a good place. Ever since his rework/nerf he has become incredibly inconsistent at killing the flankers he's designed to deal with, which combined with his equally inconsistent and buggy hook has resulted in him quickly becoming not only the worst tank, but also objectively one of the worst heroes in Overwatch.

If you're willing to indulge a bit of a rumor, I've heard that they are looking to allow him to use his Take a Breather (heal) ability while shooting, hooking or even firing his ultimate. Personally, I hope this is not true because it's a completely unnecessary change. All Roadhog needs is to have his weapon numbers adjusted so he can properly punish overextending Tracers and Genjis, as well as his numerous hook bugs corrected so that heroes like Lucio won't do a loop-de-loop if they're ever caught at high speed. These two changes alone should bring Roadhog back in a big way, especially now that slippery heroes like Doomfist, Sombra and Hammond are all the rage.

Once Blizzard releases more details, or the patch itself, I'll make sure to let you know. Until then, I wish you the best of luck with getting your favorite Halloween Terror skins!
